Public bug reported: July 2012 UEFI Specification 2.3.1C adds: An OS Indications Variable (OSIndications) - OS/FW feature & capability communication – when implemented, allows end-users to make an OS menu request to enter firmware/BIOS setup after next reboot.
This feature is already available in the Windows GUI. It would also benefit Ubuntu command line users too when booting using an EFI stub directly into the kernel (efistub boot) and with Ultra Fast Boot enabled. With Ultra Fast Boot there is no keyboard available during POST to enter firmware setup. Note: such machines are booting without grub. There might be an option to do this using selected Boot0000 option and the efibootmgr command, however some firmware has no "Setup" option listed in any of the efibootmgr boot menu entries. Expected: $ shutdown --firmware (to enter firmware on next boot) A patch for shutdown has already been written by Red Hat/Peter Jones: <http://lists.freedesktop.org/archives/systemd-devel/2013-January/008216.html> <http://comments.gmane.org/gmane.comp.sysutils.systemd.devel/8109> ** Affects: upstart (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1361319 Title: Support for enter UEFI firmware stup utility using shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1361319/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
